IMPROVEMENT IN HAY AND STRAW-GUTTING MACHINE.

TO ALL WHOM IT MAY CONCERN:

Be it known that YLYOHARLES Bnown, of the city of'Bnflalo, county of Erie, and State of New York, have invented a new and improved Hay and Straw-Cutting, Crushing, and Winnowing-Maehine; and-I do'hereby declare the following to be a full, clear, and exact description thereofl reference being hadto the accompanying'drawings, making a part of this specification.-

The nature of my invention consists--- First, in the combination oi" a cutting-mechanism with a crushing-mechanism, when they are so arranged in relation to each other as that the hay or straw cut by the first-will fall to and be acted upon by the second,

whereby the cutting and crushing of the haw or straw may be eii'ected by a single handling thereof.

'Second in the combination of a cutting-mechanism with a winuowing or cleaning-mechanism, when they are soarranged as that the hay or straw cut by the first will fall through and be acted uponby the second,

1 whereby the cutting and cleaning of the hay may be effected by a'single handling thereof.

' Third, in a cleaning-mechanism, composed of a vertical ehamber through which the cut hay falls, the back and front sides of the chamber having apertures'to permit the passage ofa current- 0f air through the chamberat right angles, or nearly so, to the falling hay, said air-current being produced by an exhausting-fan, arranged in combination with the cleaning-chamber, and separating and carrying off the fine dust,;dirt, and grit from the hay. i

Fourth, in thecombination, withthe crushing-rolls, of a dividing or-separating plate, so arranged that as the hay is thrown oil from the rolls by centrifugal action, theheavier-portions thereof will pass over the plate, while the light ehafi' will pass under the same, thus efl'ectingjtheseparation of the'chafl' from the good hay.

Fifth, in a feeding-table, composed of parallel or slightly-diverging slats, laid so as to leave openspacesi between, through which smalb'stons, sticks, dirt,-&c.,'may sift from the hay asit falls upon and passes over the same. i

efiectually to the action of said rolls. In the accompanying drawings Figure I is a sectional elevation of my improved machine. Figure II is a partial plan of same. Figure III is a'p'artial side elevation of same. Figure IV is a planet feed-table and apron. V t Figures V and VI are detail views of front'and back sides of cleaning-chamber. Like letters refer to like parts in each of the figures.

Sixth, in the combination of 'a rotary feeder with the crushing-rolls, to deliver the cut hay uniformly and A A. represent two parallel 'sjde frames, of wood, upon and between which are located the various parts of the cutting, cleaning, and crushing-mechanism. Bisthe cutter-shaft, running in journal-bearings secured to the top rails of the side frames, and carrying at the extr'emities of radial arms the cutting-knives O G, which out against the stationary bar or knife G i i i D D are feed-rollers, arrangecl in close proximityto the cutters, the cutting-edge of knife C being on line with lower side of upper feed-roller D, which runs in stationary bearings, so that hay, as it enters between the feed-rollers, will pass under the knife G, and the rotary knives act thereon with an upward out.

The lower roller, I), is held against the upper by the yielding pressure of a spring, D acting through the rod D yoke D, and radius arms D which yielding pressure-caiises the rollers to seize and carry forward the layer of hay under the ordinary variations in the thickness thereof. The rollers are driven by a series of gears from the cutter-shaft, as shown at e e e e, &c., under a'common'and well-known arrangement for such purpose. Both feed-rollers and cutters are covered by an enclosing case, D. i

The lower roller, '1'), further carries one end of an endless belt or apron, F, the opposite end of which is 3. The vertical plowing-chambers, with air-zipermres in the front and back sides thereof, and exhaustingfan combined therewith, substantially as described, and for the purpose set forth.

4. The dividing and separating-Plate L; arranged in the manner and for the purpose set forth.

5, The feed-table Gr, Constructed and irranged as described, for-the purpose set forth.

6. The rotary feeder K, arrahged and operating as set forth. v
